Average power gains over the flapper style air vane meter? Lindsey Quad-M came in today, and about to install...just curiosity. 55# injectors and Super 53 turbo

You usually don't get power "gains", but you get better drivability. If you were maxing out the AFM prior than you can see gains.

You should find a local dyno and do a before and after

I'm with Josh on this one. It would be nice to see the power gains from a dyno.

I am about to do the same to my car but with an older MAF2. Are you going to run the Power Perfect or Mafterburner softwear? I just got the turbo and 3 piece crossmember in the mail today!

Adam Poland

For now I am just tuning the from the MAF. I will be using power perfect eventually lol. I would take my car to a dyno, but I live in the corner of podunt, so I dont have any closer than 2 hours away. Plus, I'm broke.

If you have the Quad-M MAF, then there is no need to get another piggyback...

Adam Poland

Ok, good to know. You seem to be pretty knowledgeable about tuning. I have a problem. Got the MAF hooked up, and uploaded the DBX file suggested by lindsey racing. The car idles fine, but when i give it throttle, the car dies. Is it just a rich/lean problem that requires tuning, or what? I'm stumped.

Rogue_Ant

Sounds like the configuration file is incorrect for your setup. I would double check that you have the DBX file for your setup (mainly for your chip/injectors).

I have been following this thread and I am new to the 951. I am curious about the MAF conversion/upgrade.

Since I am still running the stock turbo and have excellent driveability I'm not sure there is any real performance gain. I figure I am running out of air anyway at 16-18psi boost with the stock turbo? Not complaining...the car runs really hard!

I do have 3" exhaust and test pipe, a K&N drop in, chipset, etc.

Adam Poland

Yeah if you still have the stock turbo/injector setup, you'll be fine the way you are. Did you plan on upgrading? lol

racerxrick

not in a hurry...even though I've had a number of very quick street/drag cars this little 151" 4cyl. pulls like mad on the top end

Adam Poland

Yes they do. mine pulls nasty when it runs lol. I haven't had this car working right for about six months now. My dad fried a DME, and it all snowballed from there...think twice before upgrading your turbo and injectors lol.

racerxrick

sage advice...I used to own a 87' Buick Turbo T Limited. I was running 12.17@112 and taking long road trips on stock injectors, downpipe and intercooler with a stock "appearing" turbo. Then I got greedy with power and it 'snowballed" from there. Cost me everything...and then some!

So far I've only been working on reliability and detail items! However, the boost is turned up!

Oh...and I caught my buddy with his pants (or boost) down in his highly modified GN, and walked away froma rolling start!
